This invention relates to new and useful improvements in a displaydevice.

One object of the invention is tOPlOVldG a device of the characterdescribed, specially designed for the purpose of displayingadvertisements and the like and is of such construction that it may bereadily mounted on a vehicle so as to be readily portable; however, thedevice may be mounted on a stationary support if desired.

A further feature of the invention is to provide an apparatus ofthecharacter described, which includes a plurality of display members witha display space on each side carrying advertisements and the like and amechanism whereby the said members may be revolved around a commoncenter as well as rotated on their axes so that the advertising matteron each side of each member will be 2 displayed.

With the above and other objects in view the invention has particularrelation to certain novel features of construction, operation andarrangement of parts, an example of which is given in this specificationand illustrated in the accompanying drawings, where in Figure 1 shows aside elevation of the device mounted on a motor vehicle and shown partlybroken away.

Figure 2 is a vertical sectional view thereof taken on the line 2-2 ofFigure 1.

Figure 3 is a fragmentary vertical sectional view taken on the line 3-3,of Figure 2.

Figure 4. is a vertical sectional view taken on the line 44 of Figure 1.

Figure 5 shows a vertical sectional view taken on the line 55 of Figure1, and

Figure 6 shows a vertical sectional view taken on the line 66 of Figure1.

Referring now more particularly to the drawings wherein like numerals ofreference designate similar parts in each of the figures the numeral 1designates the motor vehicle as a whole on which the device may bemounted. Upstanding from the vehicle body are the front and rearsupporting members 2 and 3 which may be formed of sheet metal, ifdesired, or other suitable material and which support the top or cover4. There is a longitu'dinal'shaft 5 rotatably mounted in suitablebearings in the respective supports 2 and 3 and fixed on the forward endof the shaft adjacent and in front of the front support 2 there is aratchet wheel 6. The device is equipped with a suitable electric motor 7which is wired in circuit with a storage battery 8, the wiring includinga switch 9 for opening and closing the circuit. Wired into said circuitthere is a clock having the usual time switch' through which the motoris in termittently connected with and disconnected from the source ofelectrical energy so that the motor will run intermittently. The timeswitch mechanism referred to is of conventioiial' construction and ithas not been thought necessary to illustrate and describe the same indetail. The shaft of the motor 7 has a wormgear 11 fixed, thereon inmesh with a corresponding gear 12 which is fixed on asuitable shaft 13,mounted in transsupport 2. As the shaft 13 rotates the pawl willoscillate and will successively engage the teeth of the ratchet wheel 6and impart a partial rotation thereto and to the shaft 5, successively.Fixed on said shaft 5 and spaced apart from the front and rear discs18,19. Between these discs there are a plurality of rotatable plate-likesign boards 20 whose opposite sides carry spaces for signs,advertisements and the like. The respective ends of the plates 20 areprovided with front and rear end pintles 21, 22, respectively, whichrotate in marginal bearings in the respective discs 18 and 19, saidshaft 5 and discs 18 and 19 forming a supporting frame. The pintles 21are" extended forwardly and have the discs 23 fixed thereon and in frontof said discs have the spur pinions 24 fixed thereon;- The discs 23 havethe oppositely disposed marginalnotches 25 and fastened to the forwardside of the disc 18 are the spring dogs 26 whose free ends 27 areforwardly turned and extend forwardly beyond the corresponding discs 23.These forwardly turned ends 27 are provided to engage in a notch in thecorresponding discs 23, to nor mally hold said disc against turning.

Fixed to the rear side of the support 2 are the upper and lower spurgears 28, 28, and carried by the rear side of said support'2 anddisposed diagonally across the path of the overturned ends 27 of thedogs 26 are the upper and lower release bars 29, 29. As the shaft 5rotates the display plates 20 will revolve wit-lithe discs 18 and 19,which are fixed on said shaft 5. The overturned ends 27 of the dogs 26will successively engage the release bars 29 and be thereby lifted fromtheir notches 25 and thereupon the corresponding spur gear 2% willengage the adjacent gear 28 and cause a partial rotation of thecorresponding plate 20, the gear ratio being such that said plate willbe given a one-half turn. As the overturned ends 27 pass the releasebars 29 they will drop down into position to engage in the other notch25 of the corresponding disc 23 so as to hold the corresponding plate 20against further rotation until again released. Inasmuch as there are twoof the gears 28 oppositely arranged each member 20 will be given onerotation with each revolution about the shaft 5 so that signs oradvertisements carried by each side of each member will be successivelydisplayed.

The operative mechanism is enclosed, and concealed from view by suitablefront and rear side hoods as 80, 31. l

The display boards 20 may be lighted at night b the electric lights 32and are connected into the light circuit of the motor vehicle.

What I claim is 1. A display device including a support, a rotatableframe mounted on said support, a display member rotatably mounted in theframe and revolvable about the axis of the frame, a releasable dogcarried by the frame and normally locking the display member againstrotation on its axis, means carried by the support arranged tosuccessively release said dog, as the frame rotates, to permit thedisplay member to rotate on its axis, and operative connections carriedby the support and display member respectively effectiveto impartpartial rotations to the display memher when said locking dog isreleased.

2. A display device including arotatable frame, supporting means inwhich the frame is mounted, a display board rotatably mounted in theframe, interlocking means carried by the display board and the framenormally locking the display board against rotation on its axis, meansfor successively releasing said interlocking means to permit the displayboard to rotate on its axis, and gearing carried by the supporting meansand displaying board through which the display board may be rotated onits axis, when so released.

3. A display device including a supporting means, a frame rotatabletherein, display members rotatable about their respective axes in theframe and revolvable about the axis of the frame as the frame rotates,means for imparting successive partial rotations to the frame,inter-meshing gearing carried by the supporting means and each displaymember respectively and operative to impart .partial rotations tosaiddisplay members, respectively, as the frame rotates, releasableinterlock ing means carried by the frame and by the respective displaymembers normally holding said display members against rotation on theirrespective axes, and means for successively releasing said interlockingmeans to permit said respective display members to be rotated abouttheir corresponding axes as they revolve about the axis of the frame.

In testimony whereofI have signed my name to this specification.
